作者在本文中提出了一种层析成像的正演和反演方法。首先对求解区作网格剖分, 由给定的正演速度模型在网格点上双线性插值, 获得整个网格节点的速度分布。然后, 对波阵面作一近似, 在此基础上, 用最小走时最短路径射线追踪法完成正演。反演则是通过正演的方法实现的。理论模型算例表明, 本方法效果较好。-In this article, the author proposed a forward and inversion of the tomography method. The mesh for solving area, by a given forward speed model grid point bilinear interpolation to obtain the velocity distribution of the whole grid nodes. Then, an approximation of the wavefront, the shortest path ray tracing completed on this basis, with minimal travel time forward modeling. Inversion is forward. The theoretical model examples show that this method is better.
